Overview:

The Whiteline Rear Sway Bar Support Braces are engineered to enhance the rigidity and durability of the rear sway bar mounting points on the Scion FR-S, Toyota 86, and Subaru BRZ models within the specified years. Designed for enthusiasts seeking improved handling precision and chassis response, these braces reduce flex and stress on the original equipment (OE) sway bar mounts. By reinforcing the mounting brackets, they help prevent bending or cracking caused by increased lateral loads during spirited driving or track use.

Ideal for drivers who demand sharper cornering and greater confidence from their suspension setup, these support braces complement Whiteline’s range of suspension upgrades to deliver a more connected and controlled driving experience.

Construction & Design:

Manufactured from premium-grade steel, the Whiteline Rear Sway Bar Support Braces are built to withstand the increased stresses placed on the rear sway bar mounts during aggressive driving. The two-point mounting system provides a solid connection that minimizes flex and distributes loads more evenly across the mounting area. The braces are precision-engineered to match the OE mounting points, ensuring a perfect fit and maintaining factory suspension geometry. This robust construction enhances the longevity of the sway bar assembly and contributes to consistent handling performance over time.

Installation is straightforward and designed to be a direct replacement or upgrade for the factory rear sway bar mounts. The braces bolt directly onto the existing mounting points without the need for drilling, cutting, or other modifications. This allows for a quick and hassle-free installation process that can be completed with basic hand tools. The product is compatible with the stock rear sway bars as well as most aftermarket options designed for the specified vehicle models.
